BarefootSevant:The whole context of these verses is about natural cycles - the solar cycle, the cycling winds, and the water cycle; that somehow the water that streams into the sea eventually returns to the streams again. These are scientifically accurate observations, and at the very least demonstrates remarkable insight, for the time.
The writer of Ecclesiastes makes some nice observations. I agree on that, he is clever. I disagree with the WT argument, which is wrong. In those verses there is no indication of divine inspiration.
